Full Answer

Triglycerides, or blood fat, put humans at risk for heart disease. WebMD reveals DHA, one type of omega-3 fatty acid, is the variety needed to lower triglyceride levels. Dr. Frank Sacks of Harvard University's School of Public Health states DHA is found in fatty fish.

Sacks also reveals omega-3 fatty acids are essential for many body functions, such as clotting blood and building cell membranes in the brain. Other health benefits include possibly preventing stroke, treating cancer, reducing inflammatory bowel disease and treating some autoimmune diseases, such as lupus.

The American Heart Association explains humans must consume more omega-3 fatty acids through foods, such as fish. Nuts and seeds offer vegetarian sources of these fatty acids, according to WebMD. Physicians can tell patients with high triglycerides to take supplements, if needed.

Omega-3 fatty acids work by producing powerful substances in the human body that strengthen natural immune responses, according to the Arthritis Foundation. The process of converting fatty acids to usable chemicals in the body cuts off the immune response, thereby preventing inflammation caused by an overactive immune system.
